Emphasis on the improvement of initiation system, experiments and three dimensional numerical investigations were carried out. Simulation results of side three initiation points fit experiments well. Optimal initiation style is obtained through further simulation. It shows that the effective fragments and the effective kill energy of the optimal scheme increase 12.8% and 10.1% respectively.展开更多

This technique has brought about obvious economic and environmental benefts, which can provide a mate-rial basis to bridge the demand gap in jet fuel supply at the new Beijing Airport and will serve as a good ex-ample of SINOPEC’s efforts in the area of transforma-tion of production mode, structure adjustment, product quality upgrading and enhancement of economic ben-efts at the refning enterprise.展开更多
